Milla Carpenter is a sixth grader with everything going for her—good friends, loving and supportive parents, smarts, and a sense of adventure. There’s just one problem: Joey Neiman. He’s the class clown with his sights set on making Milla’s life miserable. When Milla runs out of room in the journal she writes in every day, she and her mother find a new one from a mysterious vendor while perusing their town’s fabled flea market. Through a little trial and error, Milla discovers that the journal grants wishes and uses it to escape the school-day tortures of Joey Neiman. All seems well, but when the journal gets into the wrong hands, it’s up to Milla to restore order before it’s too late.
